CONNECTING TO DIODE LASER
Figure 5 shows the location of the LDD-
100/150/250 output terminals. Connect diode laser load to the output terminals.
Consult standard wire gauge tables to ensure proper gauge wire with respect
to maximum output current.
Although CW diode laser applications are
generally free of voltage spikes associated with high speed Quasi-CW
applications, it is still good practice to keep connections between the diode laser
and power supply as short as possible to avoid I
2
R losses in the wire.

INTERFACE CONNECTION
Connect user system to 15 pin D-sub connector
shown in Figure 4. (Although the user interface is typically designed by the user,
Lumina Power can provide any assistance necessary to modify interface program
and monitor levels) See Table 1 and Figure 3 for description of LDD-100/150/250
Interface and the associated simplified interface schematic.
IMPORTANT INSTALLATION NOTES
•
LDD-100/150/250 diode drivers are air cooled by internal fans. Do not
restrict air flow near the input or output air vents of the power supply. If the
unit overheats due to restricted air flow, it will shut down and remain off
until the unit has cooled to a safe operating temperature.
•
LDD-100/150/250 units should be mounted in systems using 8-32 (or M4)
bolts to secure the mounting flanges to mounting plate.
SAFETY WARNING
Because LDD-100/150/250 units are designed for OEM applications, the user
must connect AC input power to the power supply. Any input AC voltage
must be considered extremely dangerous and extreme care must be taken to
connect AC input power to the unit.
